All calculations are instant and private — no data is ever sent to a server.
The standard restaurant tip in the US is 15–20% for good service, with 20% being the most common benchmark. For exceptional service, 25% or more is appropriate. For buffets or counter service, 10% is common. Coffee shops and quick service typically see $1–2 per order.
To calculate a 20% tip mentally: move the decimal one place left to get 10% of the bill, then double it. For a $42.50 bill: 10% = $4.25, doubled = $8.50. Or simply multiply the bill by 0.20. Our tip calculator does this instantly for any percentage.
To split a bill: add the tip to the total bill, then divide by the number of people. For a $85 bill with 20% tip ($17), total = $102. Split between 4 people = $25.50 each. Our tip calculator handles any number of people and optionally rounds up to the nearest dollar for easy cash payment.
There is no universal rule, but most etiquette guides suggest tipping on the pre-tax bill amount since the tax is paid to the government, not the server. However, tipping on the post-tax amount is also common and appreciated. The difference on a typical restaurant bill is usually only $1–3.
In 2026, 20% has become the standard expected tip at full-service restaurants in the US, up from 15% a decade ago. 18% is still considered appropriate for adequate service. Some restaurants now add automatic gratuity (usually 18–20%) for large parties of 6 or more. Check your bill before adding an additional tip.
